2024 Payable 2025 Property Taxes

Property taxes were due in two installments on September 16, 2025, and November 13, 2025. Penalties for late payments on the first installment began on September 17, 2025. Late penalties are 1½% per month or any part of a month, as required by Illinois law. 

However, due to some unusually high tax increases for certain properties this year, the County Board has approved a 60-day extension on each installment before late penalties apply for bills that increased by more than 50% compared to last year. If you believe this may apply to your bill, please review the details below the tax schedule.

Pay late property taxes in the County Clerk's Office

Payments in any amount are allowed between Jul. 29 and Feb. 26. Amounts paid after installment due dates will have a 1 ½% penalty charge for each month or any part of a month.

IMPORTANT: Extra Time to Pay if Your Tax Bill Went Up Over 50%

If your 2024 property tax bill (due in 2025) increased by more than 50% from last year, you may get 60 extra days to pay for each installment before late fees begin. This extension was approved by the County Board to help with some unusually high tax increases this year.

For those who qualify, late fees begin after these dates:

First payment late after: November 16, 2025
 (4.5% plus 1.5% more each month)

Second payment late after: January 13, 2026
 (4.5% plus 1.5% more each month)

Not sure if you qualify? 
 Call 618-687-7350 and we will check.

 Call us - we can help you fix that.

Any parcels with a delinquency on December 2, 2025, will incur a $10.00 certified mailing fee, regardless of the tolling of interest. Additionally, payments made after the second installment due date remain subject to being published in the delinquent tax notice, entry of judgement, and exposure to the annual tax sale.

Past due property taxes for prior years must be paid in the County Clerk's Office.

The Jackson County Treasurer's Office's role is to collect taxes, but we do not have the authority to set the amount, change the amount of the bill, or change mailing addresses. Please see the below pages for the information you may need:
